Jakob Rieser works on the experiment that showed non-reciprocal optical interactions between two optically trapped nanoparticles. (Courtesy: Iurie Coroli, University of Vienna) When two particles are levitated in the focus of a laser beam, light reflects back and forth between them to form standing waves. The interaction with these standing waves causes the particles to

Nanostructured diamond capsules (NDCs) with high-pressure argon nanodomains embedded in the matrix. (Courtesy: Charles Zeng) High pressures dramatically change the properties of materials, sometimes producing physical and chemical characteristics with useful applications. The problem is that these desirable properties usually disappear once the materials leave the bulky vessels that make such high pressures possible. Now,
